HELP!! Can't find servers!!!

I downloaded the game and when I try to connect to a list of servers to play and it says there are none to be found or that a connection cannot be established. Can some one tell me a way to fix this or at least give me the address of a good server I can play on. Thanks.:cry:

check the filters in esf
also if you have a firewall it might be blocking half-lifes connection

hey i had tht same problem go here www.allseeingeye.com when u go there download the all seeing eye and then click half life then go down and press tghe esf icon in the menue then click the blue and red arrows and boom there aee like 30 servers
